Warning Notes
a Death may result from contact with high volt-ages. Always take extreme care and
observe the accident prevention regulations in force.
b Always disconnect the power supply to the pump before maintenance work. Place a
special warning signs over the power supply breaker switch: MACHINE UNDERGOING
MAINTENANCE - DO NOT POWER ON.
c If you are performing maintenance after the pump has been operating for a
considerable time, allow sufficient time for it to cool as the external surface
temperature may be in excess of 60 °C.
d Failure to provide the pump with an earth con-nection may cause serious damage to
opera-tors. Always ensure that there is an earth connection and that it complies with
the standards.
e When cleaning the pump and its component parts, avoid the use of flammable or toxic
solvents, such as benzin, benzol, ether or alcohol. The recommendation is to use a soap
and water solution, preferably in ultrasound washing machines, taking care to dry all the
cleaned parts at temperatures under 100 °C in order to eliminate residual moisture.
f Prolonged overloads or breakdowns may cause the electric motor to overheat,and to
release noxious smoke; remove the power immediately as a precaution and do not
approach the pump at least until you have pro-vided ventilation to drive out the smoke.
Take care not to breathe in the fumes remaining inside the pump in the course of repair
work.
g In case of fire, do not throw water on the pump. Switch the power off and use CO
2
extinguishers.
h Carefully inspect the flanges to ensure that there is no dust, oil, dirt or defects of the
mating surfaces, before making the required connections.
i Ensure that all joints and couplings are locked correctly before starting the pump again
after repair work.
